Regular season Defending champions
Herediano topped the season undefeated with 54 points. By achieving this, Herediano broke two records in the league. They became the first team with the longest undefeated streak (surpassing the 21-match streak by
Saprissa in the 2003–04 season, the team being coincidentally managed by
Hernán Medford). The team also broke the record for more points achieved in a regular season, surpassing
Alajuelense in the
2014 Invierno season. On 3 September 2017, the match between
Saprissa and
Grecia was suspended at the 81st minute due to a false bomb threat. The remaining nine minutes were played the next morning.
